Multiple Destinations for a Publisher or Subscriber

With Message Queue 4.2,
a publisher can publish messages to multiple topic destinations and a subscriber
can consume messages from multiple topic destinations. This capability is
achieved by using a topic destination name that includes wildcard characters,
representing multiple destinations. Using such symbolic names allows administrators
to create additional topic destinations, as needed, consistent with the wildcard
naming scheme. Publishers and subscribers automatically publish to and consume
from the added destinations. (Wildcard topic subscribers are more common than
publishers.)
